IMPROVEMENT IN LUBRlCATORS.

Specification forming part of Letters Patent No. lllilll, dated January7, 1873.

To all whom it may concern:

Be it known that I, JOHN McLURE POWER, of Port Discovery, in the countyof Jefferson and Territory of Vashington, have invented a new and usefulImprovement in `Lubricators, of which the following is a specication:

This invention relates to the construction ot' lubricators forsteam-engines; and consists in a novel construction and arrangement ofparts hereinafter described.

The drawing represents a vertical section of my improved lubricator.

Similar letters of reference indicate corresponding parts.

A is the neck oi' the lubricator, which is screwed into thecylinder-head, or other part. Bis the reservoir. O is the oil-receiver.D is a pipe, which is connected with the branch E from the neck A, andwith the condenser F, through which steam is admitted from the cylinder.This pipe enters the condenser and is closed at its end. It has a shortvertical branch-pipe, f, screwed into it. Gis a valvespindle attachednear the bottom of the reser voir, for drawing oitl the surplus water ofcon- H is a spindle-valve in the cup or receiver C, by which the flow ofoil is controlled, and the condensingsurt'ace increased or diminished.This spindle may be made hollow for the purpose of presenting` anincreased condensing-surface when required. I

is a solid plug, made of any non-conducting material, which closes thetop ofthe neck-tube A. Steam will pass up through the branch E and pipeD from the cylinder into the condenser, which steam will be condensed inwhole or in part, and the water ot' condensa tion will fall by its owngravity into the reser voir B. The water, being of greater specificgravity than the oil, will settle at the bottom ot' the reservoir, andwhen it accumulates in too great quantity it is drawn off through thevalve G. The lubricating-oil Hows over into the pipe D, and reaches thecylinder by virtue of its own gravity. The flow of steam upward as wellas of oil, may be shut off by means of the valve-spindle J. All thevalvespindles are arran ged so that they can be reground in their seats,and are provided with screw-caps K, and hand-rims L, the former forsupporting and inclosing and the latter for turning them.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A lubricator having a neck, A, rescrvoirB,oil-chamber C, condenser F and spindle H, cock Gr, branch E, pipe D,valve-spindle J, and plug I, when the same are arranged substanti-allyYas and for the purposes described.

JOHN MCLURE POWER.
